PROBLEM TO BE SOLVED: To provide a fuel injection valve in which not only an O-ring but a grommet can be used for sealing the interval between the fuel injection valve and an induction conduit. SOLUTION: A support disc 15 is attached to a projection 2a of a housing 2 installed to cover the outer periphery of a solenoid device and a needle valve 10, etc., with a snap fit. The support disc 15 protects the O-ring 18 for sealing the interval between the fuel injection valve 1 and the induction conduit, and maintains the grommet 17 when sealed by the grommet. An elastic seal material 16 is installed in a groove 15b installed in the inner peripheral surface of the support disk 15. COPYRIGHT: (C)2007,JPO&INPIT
